Working Principle of IRLZ44N
The IRLZ44N operates by applying a positive voltage to the gate relative to the source. When the gate voltage exceeds the threshold, a conductive channel forms between drain and source, allowing current to flow. As a logic-level MOSFET, it reaches low on-resistance at relatively low gate voltages, making it suitable for digital control circuits.
